VV5430
DESCRIPTION
The VV5430 is a highly-integrated VLSI camera device
based on the unique CMOS sensor technology from
STMicroelectronics. It delivers a fully-formatted composite
monochrome video signal. Standards options include EIA
(320 x 244) and CCIR (384 x 287).
It is possible to develop a single chip video camera using this
device that requires only supply voltage in, and delivers
composite video out for connection to a video monitor.
The integrated 75
driver eliminates the need for additional
active components to drive standard loads, including double
terminated lines.
It is also suitable for applications requiring the digitisation of
the video signal or external microprocessor control.
In the VV5430 Frame, Line and Pixel timing signals are
provided to facilitate pixel-locked digitisation of the analog
video data. In addition to the these outputs a synchronisation
input (SIN) is also provided to allow the start of frame to be
synchronised to an external event.
The device features automatic exposure control that allows a
fixed-aperture lens to be used, and incorporates Normal and
Backlit modes to give operation over a wide range of scene
types.
A bi-directional serial interface on the VV5430 allows an
external controller to set operational parameters and control
exposure and gain values directly.
